I've used a self created ID3 tags since more than 10 years and all work best. But now I had the idea to show one additionally in the statusbar of the default UI.
When you configure it, you can see it working but afterwards it will not shown.
See the embedded picture.
A known error?
Seems to me like you are using Columns UI but are trying to edit the (similar) setting corresponding to Default UI.
Try editing here instead: File/Preferences/Display/Columns UI/Status bar
Thanks a lot,
that was the 'fault' ... as most a 'level 8' problem. ;D
